Design of an active one-degree-of-freedom lower-limb exoskeleton with inertia compensation
Limited research has been done on exoskeletons to enable faster movements of the lower extremities. An exoskeleton’s mechanism can actually hinder agility by adding weight, inertia and friction to the legs; compensating inertia through control is particularly difficult due to instability issues. The added inertia will reduce the natural frequency of the legs, probably leading to lower step freq...

متن کاملAn index finger exoskeleton with series elastic actuation for rehabilitation: Design, control and performance characterization
Rehabilitation of the hands is critical for the restoration of independence in activities of daily living for individuals exhibiting disabilities of the upper extremities. There is initial evidence that robotic devices with force-control-based strategies can help in effective rehabilitation of human limbs. However, to the best of our knowledge, none of the existing hand exoskeletons allow for a...
متن کاملLower-Limb Wearable Exoskeleton
There are numerous causes that can affect the functioning of the human locomotor system, leading to the appearance of joint disorders in the lower limb and generating atypical gait patterns. The importance of research and development in assistance technologies to compensate pathological gait have been recognised since the beginning of the twentieth century and numerous challenges still lie ahea...
متن کاملTorque Analysis of the Lower Limb Exoskeleton Robot Design
Exoskeleton is a type of wearable robots that can augment the performance of an able-bodied user. There are many studies that use hydraulic actuator to actuate the lower limb exoskeleton which possesses several drawbacks like dirty, noisy and high power consumption. Therefore, electrical actuators that are clean, silent and less power consuming are used in designing the lower limb exoskeleton i...
